A couple days ago I got an e-mail notification about the latest release of CCleaner (V4.03) and so I decided to download it and run it. All seemed to go fine, but immediately after running it I noticed that most pages in Firefox weren't loading right. The results vary by the page I'm trying to load, but generally speaking, graphics don't load at all and the text often displays as a larger font size. Links that should be click-able are not. For example, Hotmail doesn't work at all. The main page seems to load okay, but I can't open a thing.
Trying to use Waterfox I get the same results. I've upgraded Firefox to the latest release with no change. At this point I can't really use Firefox at all, which had been my primary browser. I'm now using IE - that seems to be okay, but that's not my preference.
Any thoughts on what happened here and how it can be fixed?
Appreciate any insight.
